I've got the Key to your Heart

I’ve got the key to your heart,
I won’t let go;
I know the person you are -
I see you glow.

I’ll find the lock and you,
You’ll want to know,
That I’ve got the key to your heart,
With love's arrow.

Opening up inside you,
Let the love flow.
I’ve got the key to your heart,
And I’ll use it.
